Application filed July 20, 1914. Serial No. 852,062.

To all whom it may concern:

Be it known that I, STEVEN T. LESTAK, a citizen of the United States, and resident of East Bakersfield, in the county of Kern and State of California, have invented certain new and useful Improvements in Steam or Air Motors and Pressure-Distributers, of which I hereby declare the following to be a full, clear, and exact description, such as will enable others skilled in the art to ovhich it appertains to make and use the same.

The objects of the invention are to provide means for developing power from steam, air, or other gaseous or fluid pressure and for applying it at any desired point of use.

The invention comprises a motor driven by means of the pressure described, applied internally thereto, and also having the function of distributing the pressure to operate other engines at predetermined localities.

The invention further comprises a rotary motor having blades which cooperate to form traveling chambers which carry the steam or other pressure producing element to exhaust openings from which the exhaust is distributed to be applied to other motors or engines in specified positions, for convenient use.

The invention further comprises the combination and arrangement of parts and construction of details hereinafter described, shown in the accompanying drawings and specifically pointed out in the claim.

In the accompanying drawings Figure 1 is a transverse section showing the combined motor and distributer and the manner of connecting the same with the source of pressure shown in this instance to be a steam generator or boiler; Fig. 2 is a similar section showing the paddles in another position; Fig. 3 is an exterior elevation of the motor and distributer; Fig. 4: is an edge View thereof; Fig. 5 is an enlarged elevation of one of the motor blades showing an ad justable point upon the bearing edge which engages the opposing paddle blade.

In these views A is a casing in which are rotatably secured the paddle wheels B and C. These paddle Wheels are provided with interengaging blades B and C. respectively, and the blades are provided with inwardly curved sides 13", C and points B C respectively. The points of the paddles on one wheel closely engage the curved sides of the opposing Wheel as the wheels revolve, and form substantially air and steam tight oints therewith, and also form substantially air and steam tight chambers, of which the casing wall forms one side as the paddles revolve in the casing. A spring pressed feather 0* on each side of each blade makes the oints tight.

As the paddles revolve within the casing the chamber inclosed between adjoining paddles retains the compressed air or steam under pressure and conveys it to one or more exhaust openings 0, 0, through which it is discharged into pipes O O and is conveyed to an engine or engines P, P positioned at any desired points. The paddle wheel shafts D, D are geared together at E, E so as to move in unison and utilize all the power, and upon one of the shafts is positioned a crank F or other driving means, by means of which power can be obtained for any purpose, as for compressing air and storing it for further use in the same or other motors.

In the figures each paddle wheel is shown to have four paddles. In Fig. 1 the starting position is shown. Here the point 1 of one of the lower paddles is placed centrally of the inlet pipe K through which compressed air or steam enters the casing, and the point 2 of the adjacent paddle on the opposite wheel is just leaving it. A chamber L is then filled and put under pressure and revolves the lower wheel until the upper wheel has revolved to the position shown in Fig. 2, when the pressure is received upon one of the upper paddles and a chamber L is formed filled with the pressure and the upper paddle wheel receives the pressure. There will always be three revolving chambers filled with pressure and conveying it to the several exhaust openings until the edge of one paddle or blade of one wheel just commences to engage the corresponding blade of the other wheel as shown in Fig. 1. This first point of engagement will always occur on a direct line connecting the center of the two shafts, as at N, Fig. 1.

In the arrangement shown in Fig. 1 a valve V can remain open between the motor and source of supply as long as the motor. is running. This valve however can be geared to open and close periodically if desired, that is to open when the blades are in the positions shown in Fig. 1 and to close when in the position shown in Eig. 2. One

point that is the one in advance on each blade can be pivoted to the blade or connected by a link M so as to'insure a perfect contact with the surface of the engaging blade. The pressurewillthen maintain the engagement.

The piping from the exhaust should be so connected as to obtain the greatest efii ciencyfrom the pressure stored in the chambers and which must be obtained from each chamber before the severalfpaddles commence to engage with each other on the center line between the wheels. For this reason two exhaust openings can be piped to unite in one pipe leading to one engine and to obtain the same amount of pressure for any one engine exhaust ports which are similarly positioned in the two portions of the casing, as adjacent ports 0, O, and pipes O, O in'Fig. l canunite to furnish pressure to that engine.

Among the advantages found in the use of this engine is that when the blades are forced out of any one chamber the pressure will not follow but will remain in the chamber and will revolve with the same until used for other purposes.

Before the chambers'have revolved to the point of being again'filled with live steam or'air under pressure, they will have a number of opportunities to exhaust according to the number of exhaust openings used.

Having described the invention what I claim as new and desire to secure by Letters Patent is:

Inacombined motor and pressure distributer, a pair of rotatable wheels and shafts, said wheels being provided with in tor-engaging blades, making constant conwith a portion of said casing which is as-- sociated with a single one of said wheels at separated points around the periphery thereof.

In testimony whereof, I hereunto set my hand this 8th day of June 191%.
